作者在第93届分析化学家协会的年会上,对近期报道的有关有机磷杀虫剂的分析方法做了如下综述——译者。 Ivey等(1978)测定了牛组织中的毒死蜱和它的吡啶酚代谢物。他们用己烷和丙酮分别提取脂肪和组织中的毒死蜱,用己烷-乙腈分配后,在硅酸柱上净化。代谢物吡啶酚用丙酮提取。脂肪提取物用己烷-乙腈进行分配,组织提取物用苯进行分配,然后在氧化铝柱上净化。吡啶酚的BSA衍生物用具电子捕获鉴定器的气相色谱仪测定。 Mallet等(1978)用Amberlite×AD-2树脂从水
At the 93rd Annual Meeting of Analytical Chemists’ Association, the author summarized the recently reported analytical methods for organophosphate insecticides as follows. Ivey et al. (1978) measured the chlorpyrifos and its pyridinol metabolites in bovine tissues. They used hexane and acetone to extract the chlorpyrifos in fat and tissue, respectively, after partitioning with hexane-acetonitrile and purifying on a silicic acid column. The metabolite pyridinol was extracted with acetone. The fat extract was partitioned with hexane-acetonitrile, the tissue extract was partitioned with benzene and then purified on an alumina column. BSA derivatives of pyridinol were determined by gas chromatography with an electron capture detector. Mallet et al. (1978) Amberlite x AD-2 resin from water
